A long day spent Googling has taught me a lot about DJ mixes and such,
but nothing about what I really want to know. I’ve little experience
with using SDL’s audio routines, but I’d like to transition between
various loops of music without a hitch. How do people do this? Is it
as simple as waiting for a zero crossing, or are there some tricks to
match beats or harmonics? Thanks!
no idea, but you might want to have a look in audacity or ardour, both are
opensource audio mixing progams, they might have some clues…On Fri, Aug 1, 2008 at 7:03 AM, Samwyse wrote:

Sorry, I guess I wasn’t clear. I don’t want to do it myself; if so, I’d
learn how to use a DJ mixing tool, like Rapid Evolution (available at
http://www.mixshare.com/software.html).
I’m interested in the situation where just the player’s character is on
screen (and the music is relatively sedate) and then a boss appears and
the music increases in its speed and intensity. The game needs to do
the transition at “any” time, since the change usually happens in
response to a player’s action. If the loops have much length, I don’t
want to wait for the current cycle to end, but I don’t want a jarring
transition, either. The good news is that I get to choose the loops so
that they are in the same or compatible keys and their beats-per-minute
are all even multiples of some greatest-common-divisor.
I imagine that there are other “cheats” available, I just don’t know
what they are. Now that I’ve written all this our, maybe I’ll go search
gamasutra again.

The simplest way to do it programatically would be a cross fade of
length determined by delta bpm. Although a jarring transition may be
appropriate for shock value.

i would use midi or some kind of tracker. changing tempo/key gets
trivial there and you get some more possibillities for free too.
( for example adding/removing tracks in realtime without having millions
of samples and loops around).
